This ebay Buy-It-Now offering provides (5) pairs of specially made to fit 1/2" drive impact socket retaining ring kits for: Milwaukee, DeWalt, Snap On, Ingersoll Rand, Hitachi, Makita, Blue Point, Chicago Pneumatic and Kobalt cordless impact wrenches. These specially engineered ring kits are concave inside and designed to fit against the rubber o'ring I provide with each split ring. These gun socket retaining rings wrap over the anvil groove o'ring for a better fit. The actual OEM anvil groove when new measures 0.099" wide. They ring kits are wider measuring 0.094" on the ring width than conventional rings which are about 0.085" wide. If you are a mechanic, professional tool repairman or DIY person you should own a set of machinist files and a caliper when doing precise measuring of these types of parts for your impact tools. It is not my responsibility to guarantee fitment of these parts on your tools whether your tool are new or used. Your own field conditions and owner tool usage determine how to make these rings fit just exactly the same way in which piston rings are fit by the engine builder to an engine. It is quite likely that these rings have perfect fitment as they are received by you from me but it is ultimately the end user (as-in YOU) who checks and adjusts the fitment of these parts.

Special Tool Advisory Here To Read Before Purchase Of This Specialized Item

They will also fit air tool anvils with this advisory that the ring groove on a used anvil may need to be smooth filed to remove burrs which would prevent proper fitment and self-adjustment of these rings as they are inserted into your impact sockets. Your anvil fitment issues are not my problem to correct or adjust for if you plan to use these rings on your tools. You are the end user and you are expected to remove burrs and make for proper fitment on your tool anvil which you have exposed to wear and usage.
